Ouya is the new hardware that is portable and weightless. The box can be very unnoticeable unlike Xbox or play station as they are very big and a bit of a hassle to take all the plugs out. They are two different types 16GB that is 129$ or for 99$ that is just 8GB. From what I heard the controller was badly made but they allow certain games to use other controllers. They also put in another great feature that allows you to try out the game and if you like it then you can pay for it and if you do not like it you do not have to pay for it.
The players are: VEVO, iheartradio, TuneIn, XBMC, Plex, Twitch.tv, and OnLive. You can also Play games, watch videos, and listen to music within OUYA, in the comfort of anywhere with of course a screen. Some say it is not very good right now but after a while they and I think that it is going to be the complete new thing for entertainment.
Also another good thing is that it does not require any cd, everything is downloadable. An issue I have is that it has only three sockets, one for power, one for the controller and one for the screen. There needs to be more sockets for multiplayer. I think they have it in an online multiplayer. I do not have this piece of hardware but hopefully I will help you find what you are looking for in entertainment.
